FLAME ARRESTING TRAP AND MANUFACTURING METHOD FOR THE SAME, AND TRAP DEVICE WITH THE SAME FOR AN INTERNAL COMBUSTION ENGINE

摘要

PURPOSE: A flame arresting trap, a manufacturing method for the same, and a trap device with the same are provided to simplify the configuration of the trapping device by controlling the flame eruption of an internal combustion engine. CONSTITUTION: A flame arresting trap comprises a plurality of trap units(110). A plurality of trap units is laminated to the top and bottom. A single thin sheet of metal is folded to be overlapped in order to make a ring shape. A first flame introduction duct(111) is upward protruded by depressing an upper plate(115a).
